Dear Stephane, I have just returned from teaching a course last week. I'm aware that the wave names have been waiting some time and will publish my comments to the mailing list this week.

Any news on the wave period and wave direction proposals ? I'm sorry to rush you, but wave products will soon be officialy launched in Copernicus Marine Service and we are expecting those standard names to be published prior. Best regards Stéphane Tarot Le 07/02/2017 à 14:12, [email protected]<mailto:[email protected]> a écrit : Dear Elodie, Thank you for reminding me about the two geostrophic names. I agree that these two are pretty straight forward. At Nan's suggestion, I've expanded slightly on our standard definition text of "geostrophic", bearing in mind that it applies equally to ocean and atmosphere circulation. So now we have: geostrophic_eastward_sea_water_velocity (canonical units: m s-1) 'A velocity is a vector quantity. "Eastward" indicates a vector component which is positive when directed eastward (negative westward). "Geostrophic" indicates that geostrophic balance is assumed, i.e. that the pressure gradient force and the Coriolis force are balanced and the large scale fluid flow is parallel to the isobars.' geostrophic_northward_sea_water_velocity (canonical units: m s-1) 'A velocity is a vector quantity. "Northward" indicates a vector component which is positive when directed northward (negative southward). "Geostrophic" indicates that geostrophic balance is assumed, i.e. that the pressure gradient force and the Coriolis force are balanced and the large scale fluid flow is parallel to the isobars.' These two names are accepted for inclusion in the standard name table and will be added in the February update. There are ten existing "geostrophic" names: geostrophic_eastward_wind geostrophic_northward_wind surface_geostrophic_eastward_sea_water_velocity surface_geostrophic_eastward_sea_water_velocity_assuming_sea_level_for_geoid surface_geostrophic_northward_sea_water_velocity surface_geostrophic_northward_sea_water_velocity_assuming_sea_level_for_geoid surface_geostrophic_sea_water_x_velocity surface_geostrophic_sea_water_x_velocity_assuming_sea_level_for_geoid surface_geostrophic_sea_water_y_velocity surface_geostrophic_sea_water_y_velocity_assuming_sea_level_for_geoid The definitions of these names will be updated for consistency with the new text - indeed the wind name definitions don't currently explain geostrophic at all. These changes will also be part of the February update to standard names. I've been having a look at the wave period proposals and will send a separate posting to the list shortly.

There have been quite a few updates of the tables since, but those names are not included yet. Is there anything I could/should do to get them included? In April, there were also discussions on the inclusion of wave standard names. The height parameters have been included in table v35 in July. But the others (mostly period and direction) are still "under discussion" on the "CF proposal page". Any news on that topic?

The standard name table is now at version 40 and the area type table is at version 5, both dated 25 January 2017. The changes to both tables have also been published in the NERC Vocabulary Server. The changes are listed below. I have also given details of the changes that went into the standard name table at version 39, published in December 2016, as I did not send those to the mailing list at the time. Mike Godin, David Lawrence, Sophie Nowicki and Elena Shevliakova have been added to the list of contributors to CF standard names: http://cfconventions.org/Data/cf-standard-names/docs/standard-name- contributors.html. The next update to standard names is planned for 21st February 2017. Best wishes, Alison --- V39 standard name changes: 1. New names a. Proposed by David Lawrence and Elena Shevliakova for the CMIP6 LUMIP experiment: carbon_mass_flux_into_forestry_and_agricultural_products_due_to_anthropog enic_land_use_or_land_cover_change (canonical units: kg m-2 s-1) carbon_mass_flux_into_soil_and_litter_due_to_anthropogenic_land_use_or_la nd_cover_change (canonical units: kg m-2 s-1) gross_rate_of_decrease_in_area_fraction (canonical units: s-1) gross_rate_of_increase_in_area_fraction (canonical units: s-1) mass_content_of_water_in_soil (canonical units: kg m-2) mass_content_of_water_in_soil_layer (canonical units: kg m-2) surface_downward_mass_flux_of_water_due_to_irrigation (canonical units: kg m-2 s-1) surface_upward_heat_flux_due_to_anthropogenic_energy_consumption (canonical units: W m-2) surface_upward_mass_flux_of_carbon_dioxide_expressed_as_carbon_due_to_ anthropogenic_land_use_or_land_cover_change (canonical units: kg m-2 s-1) tendency_of_atmosphere_mass_content_of_carbon_dioxide_expressed_as_car bon_due_to_emission_from_forestry_and_agricultural_products (canonical units: kg m-2 s-1) b. Proposed by Paul Durack for the CMIP6 OMIP experiment: mole_concentration_of_dissolved_inorganic_phosphorus_in_sea_water (canonical units: mol m-3) 2. Aliases During the discussion of the LUMIP names it was agreed that the phrase "forestry and agricultural products" would be used in standard names in preference to "products of anthropogenic_land_use_change". This affected one existing name which has been updated as follows: carbon_content_of_products_of_anthropogenic_land_use_change (kg m-2) -> carbon_content_of_forestry_and_agricultural_products (kg m-2) --- V40 standard name changes: 1. New names a. Proposed by Sophie Nowicki for the CMIP6 ISMIP6 experiment floating_ice_sheet_area_fraction (canonical units: 1) grounded_ice_sheet_area_fraction (canonical units: 1) land_ice_basal_specific_mass_balance_flux (canonical units: kg m-2 s-1) land_ice_basal_upward_velocity (canonical units: m s-1) land_ice_runoff_flux (canonical units: kg m-2 s-1) land_ice_specific_mass_flux_due_to_calving (canonical units: kg m-2 s-1) land_ice_specific_mass_flux_due_to_calving_and_ice_front_melting (canonical units: kg m-2 s-1) land_ice_surface_melt_flux (canonical units: kg m-2 s-1) land_ice_surface_upward_velocity (canonical units: m s-1) land_ice_surface_x_velocity (canonical units: m s-1) land_ice_surface_y_velocity (canonical units: m s-1) temperature_at_base_of_ice_sheet_model (canonical units: K) temperature_at_top_of_ice_sheet_model (canonical units: K) tendency_of_land_ice_mass_due_to_basal_mass_balance (canonical units: kg s-1) tendency_of_land_ice_mass_due_to_calving (canonical units: kg s-1) upward_geothermal_heat_flux_at_ground_level_in_land_ice (canonical units: W m-2) water_flux_into_sea_water_from_land_ice (canonical units: kg m-2 s-1) b. Proposed by Mike Godin mass_concentration_of_petroleum_hydrocarbons_in_sea_water (canonical units: kg m-3) 2. Aliases No new aliases were created at version 40 of the standard name table 3. Modifications to definitions of existing names The definition of one existing name, land_ice_surface_specific_mass_balance_flux (kg m-2 s-1), was modified to make the wording more consistent with that of the new land ice mass balance names. --- V5 area type changes: 1. New area types a. Proposed by David Lawrence and Elena Shevliakova for the CMIP6 LUMIP experiment primary_and_secondary_land urban b. Proposed by Sophie Nowicki for the CMIP6 ISMIP6 experiment ice_sheet floating_ice_shelf grounded_ice_sheet 2. Modifications to definitions of existing area types a. Proposed by David Lawrence and Elena Shevliakova for the CMIP6 LUMIP experiment A second sentence was added to the definition of the area_type 'pastures', which now reads 'Pastures are assumed to be anthropogenic in origin. They include anthropogenically managed pastureland and rangeland.' --- ------ Alison Pamment Tel: +44 1235 778065 Centre for Environmental Data Analysis Email: [email protected]<mailto:[email protected]> STFC Rutherford Appleton Laboratory R25, 2.22 Harwell Campus, Didcot, OX11 0QX, U.K. _______________________________________________ CF-metadata mailing list [email protected]<mailto:[email protected]> http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata _______________________________________________ CF-metadata mailing list [email protected]<mailto:[email protected]> http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata _______________________________________________ CF-metadata mailing list [email protected]<mailto:[email protected]> http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
